Research Interests
My research focuses on high resolution investigations in the sedimentary record for natural variability, change, and events, as well as environmental impacts of anthropogenic activities/events. This includes the refinement of short-lived radioisotope geochronology (primarily excess 210Pb, excess 234Th) combined with high-resolution (mm) scanning elemental techniques (XRF) and sediment texture and bulk composition to define the sedimentary signature of events. Projects include investigations in the Gulf of Mexico including the impacts of the Deepwater Horizon oil spill, West FL Shelf, Tampa Bay, St. Lucia, Dominica, US Virgin Islands, and Cuba.
